Abstract

A 60 GHz cavity-backed antenna array integrated on high-resistivity silicon is demonstrated. The antenna design makes use of Through-Silicon-Vias (TSV), silicon micromachining, and wafer-to-wafer bonding to meet the bandwidth and radiation gain requirements for short-range multi-Gbps communications. The fabrication process is presented. Simulated and experimental results show that the antenna element covers easily the 57-66 GHz standard band with good impedance matching and more than 5 dBi of gain. Several fixed-beam four-element antenna arrays demonstrate the capabilities for beam-steering across a range up to ±60°.
